FRANK LAN'IIIIERI AND GABRIEL LANTIERI, or NEWARK, NEW'J'EBSEY;

nnmawnvme HEATER.

i T o alZ whom may concern I Beit known that we, FRANK LANTIERI andGABRIEL LAN'rmRI, bothresidin at Newark, in the county ofEss'ex and tateof New Jersey, have invented certain new and .useful Improvements inHair-Waving Heaters, of which the following is a specification.

. This invention relates to improvements in heating'devices, and moreparticularly to a new 'and improved electric heater adapted to be usedin permanent hair. waving.

One of the objects of the invention is to provide a heater of the abovetype, which canbe manufactured cheaply, and is exceedingly light inweight. g

AQfurther object of the invention is to provide a new and improvedadjusting device, whereby twolor moreheaters may be connected with asingle lead orf'cable, and the relative position of the heaters conven-,ientl y adjusted to meetthe requirements of waving hair upon the heatof a living subject.

Other objectsand aims of the invention, more or less specific than thosereferred to above, will be in part obvious and in part pointed out inthe course ofthe following description of the elements, combinations,arrangements of parts and applications of principles,.constituting theinvention; and the scope ofprotection contemplated will be indicated inthe appended claims.

In the accompanymgdrawings, wherein we havefshown a preferred formofembodiment of our invention:

Figure 1 is a longitudinal sectional View,

taken through one of ourirnproved heaters.

, Fig. 2 is a transverse sectional view, taken on line 22 ofFig. 1,looking in the d1rectionofthe arrows and Fig.3 is an jelevatlonal view,showing the manner of connecting and adjusting a' pair of heatersconstructed in accordance with the presentinvention.

Referring now to the drawing, wherein similar reference characters referto similar parts throughthe views thereof, the referencenumeral ,1denotes a cylindrical shell, preferably formed of 'meta1,the ends ofwhich are slightly flared, as at 2 and 3.

Mounted upon one end of the cylindrical shell 1 is a ring 4, preferablyformed of in 1 sulatin 56' material, suchlfor instance as presse 'mica,asbestos, or other relatively solid insulating material.

Specification of Letters Patent.

' PLatente-d May 24, 1921,

Application filed November 26,. 1919. Serial No. 340,896.

which are fastened to terminal members 7 and 8, comprismg screws mountedin the mner wall of 'the. ring or collar 4, openings 9 and 10 extendingthrough the collar to accommodate the. leading-1n wires 11 and 12.

Mounted upon the ring or collar 4 is a shell 13, the same beingositioned thereon with a relatively tight as it extends toward theopposite end of the heater, decreases in diameter as shown, until theinner end is substantially in contact with a sheet of mica 14 whichprovides an insulating layer over the resistance wire 6.

The shell 13 is provided with a projection 0r flange 15, whichextendsendwise, parallel with the heater, adjacent the cable 16, whichcarries the leading-in -wires,which cable 16 is firmly bound to theflange 15, as by means of asbestos twine 17, which layer of asbestostwine is referably solidified b insulating cement, thusproviding ahandle by means of whichthe heater may be manipulated. The mica sheet 14is located exteriorly of the resistance wire 6, is covered by a layer ofinsulating material 18, preferably asbestos'twine, whereby the micasheets and resistancewire are firmly fastened about the metallic shell1, the ends of the mica sheets 'and the resistance wire extending in thespace formed between the cylinder shell and shell-13.

.It will be noted that the layer of asbestos twine which may or may notbe solidified as by means of the insulating cement, rests against theflange 2 of the cylinder '1 and engages the end 19 of the shell 13.

Thus it will be seen that the entire device is held together without theuse of screws or rivets, making it very easy to assemble, and roviding'astructure in which the parts are not liable to become loosened orseparated.

Referring now to Fig. 3 of the drawings,

it will be noted thatcables 20 and 21 are t, and said shell,

formed block, having apertures in which the cables 20 and 21 lit with aslight frictional engagement, the cable 20 leading through the block24:, through the heater 25, and the cable 21 leading through said blockto the heater 26. In giving to the hair a permanent waving form appa'atus is customarily employed in practice having a number of suspendedheaters, and it is necessary to adjust and arrange the positions of theheaters to relieve or prevent any straining or pulling of the hair ofthe subject. In applicants construction, as fully illustrated in Fig. 3,conductors joined into a single cable are divided to form branches atthe end of the cable, and the branches lead to a pair of heaters. Thesliding block engages both branches and holds them together thus ineffect making those branches shorter or longer as may be required. Inother words,

where several heaters are simultaneously inoperation upon the hair of asubject, the members of each pair of heaters constructed in accordancewith this invention are engaged by neighboring or adjacent strands ofhair, and it is not desired that such associated heaters shall beinadvertently separated farther than intended. The heaters havesubstantially the same external appearance and when the hair-dresser isbusy and attempts a rearrangement of the heaters hastily, it is an easymatter to mistake the members of one pair for individual members ofanother pair. If the members of any pair of heaters should beunintentionally and abruptly separated too far the hair would beviolently pulled with disagreeable if not inj urious consequences. Byadjusting block 2a such a separation is prevented.

By means of this construction it will be noted that the number of cablesleading from the connection or chandelier usually employed in this workis cut in half, the heaters are more easily manipulated, and moreover,by manipulating the cables 20 and 21 through their apertures in theblock 24, the relative positions of the heaters 25 and 26 upon the headmay be conveniently adjusted.

It will accordingly be seen that we have provided a construction welladapted to attain, among others, all the aims and objects above pointedout, in an exceedingly facile manner, the heaters are cheap tomanufacture. easy of assemblage, in that no screws or rivets arerequired. Moreover, the construction is such that there is nothing aboutthe heater to become disarranged, nor is there any likelihood of theinterior heating or resistance wires becoming short-circuited, the partsbeing all positively held in fixed relation. The arrangement of theheaters in pairs is also convenient, as well as eco nomical.

is many changes could be made in this construction without departingfrom the scope of the following claims, it is intended that all mattercontained in the above description or shown in the accompanying drawingshall be interpreted as illustrative only and not in a limiting sense.

Having thus described our invention what we claim as new and desire tosecure by Letters Patent is:

1. In a device of the character described, the combination with a hollowcylinder having flanged ends, of a collar of insulating material mountedupon the said cylinder and seated against one of the said flanges,layers of insulating material surrounding the said cylinder, a coil ofresistance wire arranged between said layers of insulation, conductorspassing through the said collar and connected with the said resistancewire, a cupped shell having its larger end encircling and in contactwith the said collar, the said shell surrounding the said cylinder andlayers of insulation and extending from the said collar for a part ofthe length of the cylinder, and asbestos twine binding encircling thesaid cylinder and insulating layers between the end of the shell and theother flanged end of the cylinder whereby the insulation, coil, shelland the said collar are secured in place.

2. In a device of the class described, a hollow cylinder having flangedend portions, a collar of insulating material mounted upon said cylinderand seatin against one or the flanges thereof, a plurrlity of layers ofinsulating material positioned upon said cylinder, coil of resistancewire positioned intermediate said layers of insulating material,leading-in wires extending through said collar, terminal members carriedby said collar and connected with said leadingin wires, said terminalmembers being also connected with said resistance wires, a shell mountedupon said collar, said collar extending rearwardly and inwardly andterminating adjacent the layer of insulating material covering saidresistance wire, a covering of insulating material disposed about theouter layer of said last named insulating material and interposedbetween the rear edge 01": said shell and the flanged portion of saidcylinder, said shell being provided with a flange which extends beyondthe first named end of the cylinder, a cable carrying the leading-inwires disposed adj acent said flange, and a covering of insulatingmaterial binding said cable and flange together.

8. The combination with a pair of heaters of the character and for thepurpose described, of conductors united into a single cable havingbranches at its end, the said branches being connected with the saidsaid branches of the cable and holding them together whereby the lengthof the said a of the character and for the purpose described, ofconductors united into a single cable having branches at its end, thesaid branchesbein connected with the said heaters, and a sliding blockhaving passages frictionally engagingthe said branches of the cable andholding them together whereby the length of the said branches may beadjusted. a
